This include made it even harder I think :P - I won't explain anything because it's happened enough already.

Code:

#define seconds(%0) (1000 * %0)
#define minutes(%0) (1000 * 60 * %0)
#define hours(%0) (1000 * 60 * 60 * %0)

SetTimer("AnyFunction", 500, false); //Half second
SetTimer("AnyFunction", seconds(5), false); //5 seconds
SetTimer("AnyFunction", minutes(5), false); //5 minutes
SetTimer("AnyFunction", hours(1), false); //1 hour

By the way, I prefer Y_Less' one.

Code:

SetTimer("AnyFunction", 500 MILLISECONDS, false); //Half second
SetTimer("AnyFunction", 5 SECONDS), false); //5 seconds
SetTimer("AnyFunction", 5 MINUTES, false); //5 minutes
SetTimer("AnyFunction", 1 HOUR, false); //1 hour
